Abstract: An assembly for a vehicle includes a dash. The assembly includes a seat having a seatback and a head restraint extending upwardly from the seatback. The assembly includes an airbag supported by the seatback. The airbag is inflatable from the seatback toward the dash in a seat-rearward direction to an inflated position. The airbag includes an upper portion adjacent the head restraint and a pair of lobes extending from the upper portion along the head restraint in a seat-forward direction in the inflated position. The head restraint is between the lobes in the inflated position.

Abstract: An airbag includes a U-shaped chamber, a head-impact chamber, and an uninflatable panel. The U-shaped chamber has a first side leg, a second side leg, and a top extending from the first side leg to the second side leg. The head-impact chamber is disposed between the first side leg and the second side leg. The uninflatable panel extends from the first leg to the second leg adjacent the head-impact chamber.

Abstract: A system includes a seatbelt retractor and a webbing payable from the seatbelt retractor. A marker is fixed to the webbing. A proximity sensor is fixed relative to the seatbelt retractor. The proximity sensor is designed to detect the marker when the marker is within sensing range of the proximity sensor. The marker is positioned along the webbing to be out of sensing range of the proximity sensor when the webbing is engaged with a 6-year-old anthropomorphic test device and to be in sensing range of the proximity sensor when the webbing is engaged with a child seat.

Abstract: A seatbelt height adjuster includes a track elongated along an axis and including a plurality of holes spaced from each other along the axis, a slider slideably coupled to the track, a D-ring supported by the slider, a pin supported by the slider and releasably engageable with one respective hole, and a pyrotechnic actuator supported by the slider and engaged with the pin.

Abstract: A seatbelt webbing includes an auxetic portion elongated along an axis. The auxetic portion includes a plurality of segments rotatably connected to each other at hinges. The hinges are spaced along the axis and are transverse to the axis. The auxetic portion includes a plurality of strands. Each strand is embedded in at least two of the hinges. When tensile force above a predetermined level is applied to the auxetic portion by a vehicle occupant, e.g., the chest of the vehicle occupant, the auxetic portion both stretches along the axis and widens transverse to the axis, i.e., has a negative Poisson ratio.

Abstract: A vehicle includes a body having two pillars spaced from each other. The body includes a rocker extending from one pillar to the other pillar. An airbag is fixed to the rocker and inflatable to an inflated position. The airbag extends outboard of the rocker in the inflated position. The airbag includes a first chamber and a second chamber substantially fluidly separated from each other. The first chamber extends farther outboard of the rocker in the inflated position than the second chamber.

Abstract: A seatbelt assembly includes a D-ring, a clip spaced from the D-ring, a webbing slideably engaged with the D-ring and the clip, and an airbag slideably receiving the webbing between the D-ring and the clip. The airbag includes a first portion, a second portion, and an intermediate portion therebetween. The first portion and the second portion are inflatable to an inflated position and the intermediate portion is uninflatable.

Abstract: A collapsible vehicular armrest substrate includes load-bearing strips extending across a gap defined within a support frame. A first tunable element secures the load-bearing strips in a support position on the support frame. A first tension-adjusting portion sets a predetermined first tension limit of the first tunable element. The load-bearing strips disengage from the support position when the first tunable element experiences an actual tension greater than the predetermined first tension limit.

Abstract: A computing device in a vehicle can be programmed to receive an occupant position measurement from at least one of an acoustic and a light sensor, determine an estimated occupant size based on occupant weight, estimate a vehicle seat position based on the occupant position measurement, and, control a vehicle occupant safety device based on the estimated occupant size and estimated vehicle seat position.

Abstract: Method and apparatus are disclosed for vehicle airbags for occupants in rear-facing seats. An example vehicle includes an instrument panel, a rear-facing seat adjacent the instrument panel and including a seatback and a headrest, and an airbag including a lower portion and an upper portion. When undeployed, the airbag is stored in the instrument panel. When the airbag deploys, the lower portion presses onto a back of the seatback and the upper portion presses onto a back of the headrest.

Abstract: An airbag system includes a center airbag, a first side-wing airbag, a second side-wing airbag, and a tether. The center airbag is disposed in a steering wheel of a vehicle. The first side-wing airbag is disposed on a first side of a support housing disposed between the steering wheel and an instrument panel of the vehicle. The second side-wing airbag is disposed on a second side of the support housing. The tether connects the side-wing airbags and is disposed above the support housing.
